Katydids of the genus Ewanella Naskrecki (Mecopodinae) and stick-like katydids of the genus Conocephalus Thunberg (Conocephalinae) are reviewed. The latter representatives are included in the subgenus Megalotheca Karny, stat. n., which was formerly considered a separate genus but is here reduced...

The article presents the first North American records of Conocephalus dorsalis (Latreille 1804) (Orthoptera, Tettigoniidae). The genus Conocephalus includes 158 species and present in all temperate and tropical regions of the world. 18 native species are in North America north of Mexico and 6...

In katydids such as Kawanaphilanartee, a female bias in the operational sex ratio (OSR) results in female competition for mates and male choice of mates. Previous work showed that the excess of sexually active females occurs when food availability is low, in part because less food increases the...

A new genus of bushcricket, Hermoniana n. gen., is erected for a new tettigoniid species. The only species of this genus, H. blondheimae n. sp., was collected at 2000 m altitude on Mt. Hermon, Israel. Platycleis (Incertana) erecta (Uvarov), described from central Israel, is synonymous with...

Katydids and crickets generate their characteristic calling sound by rubbing their wings together. The mechanisms of the rubbing force, however, have not been extensively studied. The change of mechanical force with external parameters (speed and applied load) in the stridulation process has not...

The two most common kinds of katydids are the northern true katydid, Pterophylla camellifolia, and Microcentrum retinerve. The male northern true katydid's song includes the sounds "Katy did," "she did," and "Katy didn't." Although not all katydids make these sounds, all share this name.

To help determine whether the typical arthropod arrangement was a synapomorphy for the whole Tettigoniidae, we sequenced the mitochondrial genome (mitogenome) of the quiet-calling katydids, Xizicus fascipes (Orthoptera: Tettigoniidae: Meconematinae). The 16,166-bp nucleotide sequences of X....
